I prefer chain texts when I am engaging in a conversation. It feels more like natural conversation. As a sentence is out of my brain, the recipient has it. Sometimes the thoughts are fully organized, there's just a linebreak between them, and it's just a formatting distinction. But there are differences between "sending a text message to relay information" and "having a conversation via SMS"
The obnoxious part is the constant vibrate/beep per incoming message, but Android has a "minimum time between notification sounds" config option though, I imagine Apple does too, so that has never really bothered me either.
